ERROR: ldd outputLine: "libmysqlclient.so.18 => not found" linuxdeployqt

[Ahsan Niaz]

Hi, I have created a project on QT creator which is linked with multiple cpp exes. Most of these exes are working with (-lsqlite3). Data base is directly linked to whole project
Process of Deployment:

• I have downloaded release from github which is named as linuxdeployqt-7-x86_64.AppImage and is placed in DOWNLOADS folder
• I have exported the path of qt by

export PATH=/home/kaleem/Qt5.9.1/5.9.1/gcc_64/bin/:$PATH

• i have created a folder named(processorder) in Downloads directory.
• (processorder) folder has three files, one is the binary named(Process_Order), 2nd file is .desktop file and the third is icon file which is in png format

after all this, i opened terminal in downloads and ran following command

./linuxdeployqt-7-x86_64.AppImage processorder/Process_Orders -unsupported-allow-new-glibc -appimage

It gave me the following errors

ERROR: ldd outputLine: "libmysqlclient.so.18 => not found"
ERROR: for binary: "/home/kaleem/Qt5.9.1/5.9.1/gcc_64/plugins/sqldrivers/libqsqlmysql.so"
ERROR: Please ensure that all libraries can be found by ldd. Aborting.

then i changed my command to

/linuxdeployqt-7-x86_64.AppImage processorder/Process_Orders -unsupported-allow-new-glibc -exclude-libs=libmysqlclient.so

but i still got same error. Can anybody help me deploy my project successfully?

you were close, the right way to exclude this lib would have been

-exclude-libs=libqsqlmysql
